FRAM combines the speed, flexibility, and endurance of SRAM with the non-volatility of Flash, offering 10^15 write cycle endurance and unified memory for program, constants, and data storage. The device features a 12-bit 200 ksps ADC, two enhanced comparators, multiple 16-bit timers, and a 32-bit hardware multiplier. Dual eUSCI_A and eUSCI_B modules provide flexible UART, SPI, and I2C connectivity. The device achieves 142 \u00b5A\/MHz active current, 1.43 \u00b5A LPM3 standby, and 42 nA LPM4.5 shutdown.","working_principle":"The MSP430FR2155 uses a 16-bit Von Neumann architecture with a constant generator that enables 16-bit instructions in a single cycle. The FRAM memory controller manages read\/write operations with ECC protection and configurable write protection. The Power Management Module (PMM) with Supply Voltage Supervisor (SVS) ensures reliable operation across the 1.8-3.6V supply range. The clock system integrates a 24 MHz DCO with FLL achieving \u00b11% accuracy, plus external crystal and internal low-frequency oscillators. The ADC uses a successive approximation architecture with sample-and-hold, while the eCOMP modules feature programmable hysteresis and integrated 6-bit DAC reference voltage generation. Low-power modes progressively disable clock domains and peripheral power to achieve sub-microamp standby and nanoamp shutdown currents.","pin_description":"\n
